How can I modify the download progress bar in the YouTube Video Downloader template to show real download progress?

To modify the download progress bar to show real download progress, you'll need to implement server-side functionality to handle the actual download and send progress updates to the client. Here's a basic example of how you could modify the home.js file to receive real progress updates:

```javascript document.addEventListener('DOMContentLoaded', () => { const form = document.getElementById('download-form'); const progressBar = document.getElementById('progress-bar'); const progressText = document.getElementById('progress-text'); const downloadProgress = document.getElementById('download-progress');

 form.addEventListener('submit', async (e) => {
   e.preventDefault();
   const videoUrl = document.getElementById('video-url').value;
   const format = document.querySelector('input[name="format"]:checked').value;

   if (!videoUrl) {
     alert('Please enter a YouTube video URL');
     return;
   }

   downloadProgress.classList.remove('hidden');

   try {
     const response = await fetch('/api/download', {
       method: 'POST',
       headers: { 'Content-Type': 'application/json' },
       body: JSON.stringify({ videoUrl, format })
     });

     const reader = response.body.getReader();
     const contentLength = +response.headers.get('Content-Length');
     let receivedLength = 0;

     while(true) {
       const {done, value} = await reader.read();
       if (done) break;

       receivedLength += value.length;
       const progress = Math.round((receivedLength / contentLength) * 100);
       progressBar.style.width = `${progress}%`;
       progressText.textContent = `Downloading... ${progress}%`;
     }

     progressText.textContent = 'Download complete!';
   } catch (error) {
     console.error('Download failed:', error);
     progressText.textContent = 'Download failed. Please try again.';
   }
 });

}); ```

This code assumes you have a server-side API endpoint at /api/download that handles the actual video download and streams the response.
